Phalaenopsis orchid plant named ‘PHALHALXYP’

ABSTRACT

A new and distinct variety of Phalaenopsis plant named ‘PHALHALXYP’, particularly characterized by white, striped flowers with red-purple lips, flat flower shape in lateral view, moderately compressed petal shape, and is propagated by meristem tissue culture, is disclosed.

Genus and species: Phalaenopsis hybrid.

Variety denomination: ‘PHALHALXYP’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar ofPhalaenopsis plant, botanically known as Phalaenopsis hybrid of theOrchidaceae family, commonly referred to as moth orchid, and hereinafterreferred to by the variety name ‘PHALHALXYP’.

The new Phalaenopsis plant is a product of a planned breeding programconducted by the inventor in Bleiswijk, the Netherlands. The objectiveof this breeding program was to create a new Phalaenopsis plant withwhite, striped flowers and red-purple lips, suitable for potted plantproduction.

The new Phalaenopsis plant ‘PHALHALXYP’ is a result of cross-pollinationmade by the inventor in July 2010 in Bleiswijk, the Netherlands, of theproprietary female, or seed parent, Phalaenopsis hybrid ‘21396-0002’(unpatented) with the proprietary male, or pollen parent, Phalaenopsishybrid ‘33408-09’ (unpatented).

The new Phalaenopsis was selected by the inventor as a single plantwithin the progeny of the stated cross-pollination in a controlledgreenhouse in Bleiswijk, the Netherlands, in July 2013. Asexualreproduction of the new Phalaenopsis plant by meristem tissue culturesince 2014 in Bleiswijk, the Netherlands, has demonstrated that the newvariety reproduces true to type with all of the characteristics, asherein described, firmly fixed and retained through successivegenerations.

Community Plant Variety Rights for this variety have been applied for inthe European Union on Sep. 25, 2018 (Application no. 2018/2458), byApplicant who obtained the subject matter disclosed directly from theinventor. ‘PHALHALXYP’ has not been made publicly available or soldanywhere in the world prior to the effective filing date of thisapplication with the exception of sales or disclosures made one year orless before the effective filing date of this claimed invention byApplicant who obtained ‘PHALHALXYP’ directly from the inventor.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Bleiswijk, the Netherlands, and can be usedto distinguish ‘PHALHALXYP’ as a new and distinct variety ofPhalaenopsis plant:

-   -   1) White, striped flowers with red-purple lips;    -   2) Flower shape in lateral view is flat; and    -   3) Petal shape is moderately compressed.

DESCRIPTION OF THE PHOTOGRAPHS

This new Phalaenopsis plant is illustrated by the accompanyingphotographs which show the overall plant habit including blooms, buds,and foliage of the plant; the colors shown are as true as can bereasonably obtained by conventional photographic procedures. Thephotographs were taken in a greenhouse in Bleiswijk, the Netherlands,from 50-week-old plants in May 2020. Colors in the photographs maydiffer from the color values cited in the detailed botanicaldescription, which accurately describe the actual colors of the newvariety.

FIG. 2 shows a close-up of a flower of ‘PHALHALXYP’.

FIG. 3 shows an overhead view of the leaves of ‘PHALHALXYP’.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘PHALHALXYP’. Plants of the new Phalaenopsis have notbeen observed under all possible environmental conditions. The phenotypemay vary somewhat with variations in environment such as temperature,light intensity and day length, without, however, any variance ingenotype. The chart used in the identification of colors describedherein is The R.H.S. Colour Chart of The Royal Horticultural Society,London, England, 2015 edition, except where general color terms ofordinary significance are used. The color values were determined under4000-6000 lux natural light in a greenhouse in Bleiswijk, theNetherlands. Observations and measurements were made in May 2020 onflowering plants which were planted in 12-centimeter (diameter) pots.After in vitro propagation, the plants were grown in nursery trays for20-24 weeks, followed by transplantation to 12-centimeter pots and grownin a greenhouse between 27° C. to 29° C. for 30 weeks, continued by acooling period of 8 weeks between 18° C. to 20° C. and 12 weeks in agreenhouse of 21° C. Flowering occurs after 50 weeks in 12-centimeterpots.

COMPARISON WITH PARENTAL LINES AND MOST SIMILAR VARIETIES

‘PHALHALXYP’ differs from female parent plant ‘21396-0002’ (unpatented)in that ‘PHALHALXYP’ has a moderately compressed petal shape andemarginated petal apexes, whereas ‘21396-0002’ has a moderatelycompressed to medium petal shape and rounded petal apexes. Additionally,‘PHALHALXYP’ has larger flowers than ‘21396-0002’.

‘PHALHALXYP’ differs from male parent plant ‘33408-09’ (unpatented) inthat ‘PHALHALXYP’ has emarginated petal apexes, whereas ‘33408-09’ hasobtuse petal apexes. Additionally, ‘PHALHALXYP’ has larger flowers than‘33408-09’.

‘PHALHALXYP’ is most similar to the commercial Phalaenopsis plants named‘PHALBUKAP’ (U.S. Plant Pat. No. 25,445) and ‘PHALFESFI’ (U.S. PlantPat. No. 31,481). ‘PHALHALXYP’ differs from the commercial variety‘PHALBUKAP’ in that ‘PHALHALXYP’ has elliptic dorsal sepals andtriangular apical lobes, whereas ‘PHALBUKAP’ has ovate dorsal sepals andobdeltoid apical lobes. Additionally, ‘PHALHALXYP’ has shorter whiskersthan ‘PHALBUKAP’.

‘PHALHALXYP’ differs from the commercial variety ‘PHALFESFI’ in that‘PHALHALXYP’ has emarginated petal apexes, whereas ‘PHALFESFI’ hasobtuse petal apexes. Additionally, ‘PHALHALXYP’ has smaller flowers andshorter whiskers than ‘PHALFESFI’.
